Can SMBDAD or others provide some follow-up on this 2008 thread? (SMBDAD, how has the Chiri Enterprise Roof-it RV held up?) We have a 1991 Sportsmobile (Dodge Ram van) with a gel coat fiberglass roof on the penthouse. The penthouse roof shows signs of age -- some hairline cracks and algae or fungal discoloration (spots) -- see photos below.
The SMB service rep I talked to said this kind of damage is probably superficial and probably doesn't cause leaks, but we'd like to do something to improve the appearance of the top and probably prevent future problems.
We'd like a smooth coating that can easily be cleaned so we can keep fungi from establishing (we live in Oregon where it's very wet in winter).
We'd also like to apply the coating over the rusted bolts, to protect them from further deterioration. Taking apart the inside of the penthouse to remove and replace the bolts is too big a job for us.
I called two Sportsmobile offices and two different service reps had very different recommendations. One recommended "Kool-seal RV rubber roof coating" ("not the rubber roof patch," he said). I found it here:
http://www.koolseal.com/product_detail. ... _id=63-900. However, when I called the Kool-seal company, the Kool-seal rep said I should NOT use the rubber roof coating because that's only for rubber roofs, not fiberglass surfaces. The Kool-seal rep recommended the standard Kool-Seal white elastomeric roof coating (
http://www.koolseal.com/product_detail. ... _id=63-600) for fiberglass roofs.
The other SMB rep recommended professionally-applied clear coat automotive paint, which seems odd for a fiberglass roof, so I haven't pursued that.
The Chiri Enterprise Roof it-RV mentioned above in this thread (
http://www.chirienterprise.com/Roof-It- ... It-RV.html) looks easy to apply and durable. I've ordered a sample but I'm nervous about applying it before I hear from other SMBers.
Can someone recommend a good product for a smooth, hard coating that we can apply to our aging fiberglass roof? Obviously we'd like something durable that won't flake or peel off.
Thanks!
